A 3D Pixar-style character portrait of Old Mechanic Walter, around 70 years old. He has warm, kind eyes, friendly wrinkled face, gray messy hair peeking out from under a grease-stained classic flat cap, and some light grey stubble. He is wearing blue denim mechanic overalls over a red checkered flannel shirt, with a small wrench visible in his pocket. The background is a cozy, softly blurred garage workshop with tools hanging on the wall. Warm, cinematic studio lighting, highly detailed 3D render, cute and expressive character design.
